TO ALL WHOM IT MAY GONOERN Beit known that I, CHARLES RICHARDSON, of the city' of Auburn, in the county of Cayuga, and State of New Yprkf. have invented certain new and useful Improvements in Machines for Grinding Reaper-Knives and I do hereby declare that the following is a full, clear,` and exact description of the vconstruction and operi tion of the same, reference being had `to the-annexed drawings, making 'apartof this specification, in which- Figure 1 represents the complete machine, with my improvements thereon, when ready to beoperatcd.

Figure 2 representsu view of a section of said machine, including the grindstone, the water-tank or reservoir, with its attachment to the grindstone-frame, and of parts of said frame.

Figure 3 represents a section of the swing-frame, and the manner of fastening the adjustable top-picce thereof.

O O are the screw-bolts, by which the adjustable top-piece of the s.ving-i`raine is fastened in any desirable position. P isA the reservoir or water-tank, directly under the grindstone M. q is the piece attached to the'side of said reservoir or water-tank, by which it is hung to the frame which supports the grindstone. r is the tongue- 4piece, formed upon or rigidly attached to said frame, to which said reservoir or water-tank is suspended.

For the explanation of' the ether parts of the drawing, reference is hereby made to the specifica-tion aridf drawings annexed to Letters Patent granted to Edwin M. Scott, otAubui-n, for Improvements in `Machines for Grinding Reaper-Knives, bearing date July 30, ISST, and numbered 67,365.

The nature of my invention consists, first, in making the top-piece ofthe swing-frame II adjustable in any desired position, and thereby enable the operator to grind the knives or sections of any desired bevel; second, in hanging the reservoir.water-taule to the framework which supports the grindstone, so that it shall at all times move with the stone, and he always in tbeisame relative position therewith.

The machine in all vother respects may be constructed as described in the speeicntion annexed to the saidpatent of said Scott, or in any other manner desired, as my improvements are not confined tov any particular pattern in regard to other parts of the machine.

In regard to my first improvement, I makethe swing-frame II with clamps I I I, for the purpose of holding' the reaper-bar while the knives are being ground. But instead oi" attaching the top part of said swing-frame, to which said reaper-bar is thus fasi-cned, rigidly to the sidepieces, I attach the saine thereto adjustably as'follows, by passing a screw-bolt, having an eye at one end thereof, through each of said side-picces, near the top thereof, and roundingIr each end of' saidtop-piece, so that the same will pass through said eyes, which enables the operator to adjust said reaper-bar and knives so that the saine shall form any desired angle with said grind- .stone, and thereby the said opgeratorpin. grinding, is enabled to form the bevel upon said linivcs at any :ingle desired'.

` In regard to my second improvement, that the water-tank or reservoir may hang direct-ly undrer the grindstone,l and be moved with it at all times, Iattech a piece, q,rgidly to the side of said water-tank arroser-voir, or the same may be castas a part thereof. Upon or in the side of this piece g, I cut agroovc to fit the tonguepiece r, whichis fastened upon or castas a part oi` one of the standards 7i, upon which the stone is hung.

Y When it is desired to use the reservoir or watentnnh, it is only necessary to ship the said groove-:l piece y upon' the tongue-picco 1^, and the reservoir er water-tank will then hang directly under the grindstone, and being fastened to and upon one of the standards It, upon which the stone is hung, it must-necessarily more with the stone whenever the position/foi` that shall be changed, thus always remaining in place directly under-the grindstone.

Having thus fully described my invention, and the several parts thereof,Y and the manner in which I contemplate using the same, and the operation und etect thereof; what I claim therein as new, and desire to secure 1. Making-the top-piece of the swing-frame H, to which the cutter is fastened when the knives nre to be ground, adjustable, and using the same in `combination with the adjustable grindstonm in the manner and for the purpose substantially as described.

2. Aixing the water-tank or reservoir P to one. oi' the standards which support the grindsone, so that the same shall at a'll times hang directly under said stone, and using the saine in combination with :in adjustable grindstone hung upon a movable plate or disk, substantially' as and for the purpose described. l
